Windows

This script is under 'Microsoft Visual Studio 10.0\VC\bin' folder. Then,

(cmd)$ qmake -r -spec win32-msvc2010 CONFIG+=release
(cmd)$ nmake

then, the binary should be here: .\src\release\bbox.exe

But don't worry: I will provide a BBoxInstaller.exe quite soon.

MacOSX

You need to Download Qt Creator and the Qt SDK in order to compile the binaries.
Then open the project in ./bbox.pro in Qt Creator Application you just downloaded, and click build.
You'll have a new folder called src-build-desktop.
Inside there you'll have a bbox.app Mac OS X bundle.

Right after that if you want to package the software in order to distribute it, you'll need to open a Terminal tab or window and type

What this command does, is basically include Qt frameworks needed for the application to run, so that those who don't have Qt SDK installed can run this too.
Now you can both install and distribuite the build.

How to install the server

The Web is full of excellent tutorials about how to install SVN (subversion) + Apache + mod_dav.
I don't want to write here how to do this step. But soon-ish I will provide a couple of good URLs
about this procedure.
